image/svg+xml SHA1NEXTE—Calculate SHA1 State Variable E after Four Rounds Instruction Operand Encoding Description The SHA1NEXTE calculates the SHA1 state variable E after four rounds of operation from the current SHA1 state variable A in the destination operand. The calculated value of the SHA1 state variable E is added to the source operand, which contains the scheduled dwords. Operation SHA1NEXTE TMP := (SRC1[127:96] ROL 30); DEST[127:96] := SRC2[127:96] + TMP; DEST[95:64] := SRC2[95:64]; DEST[63:32] := SRC2[63:32]; DEST[31:0] := SRC2[31:0]; Intel C/C++ Compiler Intrinsic Equivalent SHA1NEXTE: __m128i _mm_sha1nexte_epu32(__m128i, __m128i); Flags Affected None SIMD Floating-Point Exceptions None Other Exceptions See Table2-21, “Type 4 Class Exception Conditions”.
